    Hello everyone,

    Like i mentioned in my other post here :
    https://www.electronicspoint.com/fo...er-interface-for-arduino.292520/#post-1795054
    I want to build my own arduino based fuel injector cleaner. Further more i have seen theese ultrasonic cleaners that work pretty well. Does anyone know how to use ultrasonic transducers ?
    I found a few on e-bay :
    https://www.ebay.com/itm/Aluminum-A...epid=0&hash=item3cf65ca776:g:NtgAAOSw34FVGgIs
    What is their rated voltage and current, how can i drive them. I suspect that it takes 30-40Khz pulses of high current but im not sure.
    Any insight is welcomed . Thank you !

    I bet the transducer itself runs on lower voltage. The driving circuit is there to turn the 50/60Hz mains supply to 28Khz . If that is the case then i could use the arduino to produce the 28Khz and mosfets to supply the pulsed voltage to the transducer.

    Well its probably the same i suppose. So the transducer and driver circuit are what i need.
